Heating cable DANFOSS DEVI 98300071 self-limiting 2 m ready-to-plug

The DANFOSS DEVI 98300071 self-limiting heating cable is a 2 m ready-to-plug solution intended for freeze protection and temperature maintenance on pipes, gutters and small surfaces. Its self-regulating design adapts heat output to ambient temperature, providing targeted warming where needed while reducing power consumption and avoiding overheating of the heated object. The product is compact and pre-terminated for straightforward connection to a standard power outlet, making it suitable for fast installation in domestic and light commercial settings.

Advantages

The self-limiting heating element automatically varies heat production along the cable length in response to temperature changes, which increases safety and efficiency compared with fixed-output heating. The 2 m length and pre-fitted plug simplify planning and installation, and the cable construction is designed for reliable operation in exterior and interior locations requiring freeze protection. Low maintenance requirements and stable performance under variable ambient conditions support long-term, energy-conscious operation.

Suitable for

• Freeze protection of water pipes in unheated spaces
• De-icing of gutters, downspouts and small roof sections
• Maintaining temperature on valves, joints and small-diameter lines
• Local spot heating for domestic and light commercial installations

How to use

Route the heating cable along the section to be protected and secure it using compatible fixing accessories; avoid sharp bends and do not overlap the cable. Connect the pre-fitted plug to a suitable grounded outlet protected by an appropriate residual current device as required by local regulations. For continuous operation, ensure the cable is installed unobstructed and inspected periodically for mechanical damage or wear. When using on plastic pipes or insulated runs, follow manufacturer guidance to ensure safe heat transfer and required spacing from insulation materials.

Usage recommendations

For reliable freeze protection, start installation from the coldest point and extend the cable along the vulnerable sections. Use DANFOSS-recommended accessories and follow local electrical codes; consult a qualified electrician for permanent or high-risk installations. Regular visual inspection before each cold season will help maintain performance and safety.
